White House press secretary Josh Earnest shared details about his media diet in an interview on CNN's "Reliable Sources" on Sunday.

Earnest, who said he’s attached to his iPad, enjoys reading The Associated Press and relies heavily on the White House's internal news clip service. He said he turns to CNN as a “good barometer of what a lot of people” in the press room will be interested in and looks to POLITICO online.

“POLITICO has certainly done a lot to really transform the way that the news is reported here in Washington. That is an outlet that I know a lot of reporters go to for news, and it's certainly one that I look for, too,” Earnest said.

When questioned about transparency at the White House, Earnest repeated the White House line that this administration has been the most transparent compared with others, to which host Brian Stelter said, "I’m surprised you still say that line.”

Earnest said that the White House press corps should always be pushing the administration for more.

“The day they sit back and say we don’t need to write a letter, the White House is telling us everything they need to, they’re not doing their jobs,” he said.
